EDH on Xmage

Hey guys, I just wanted to make sure I'm not doing anything wrong there. I tried playing Commander on XMage and its really rough, the lag and delays make it nigh impossible to do a 4 player game. Is it something on my end/bad luck, or is that just something the app can't quite handle atm?
Also, anoteher wierd thing, I cannot target the top right player or any of their permanents at all. Its like that part of the board is excluded from the game for me. It fixes itself when the top left player goes down and the layout changes, but before that its bugged.
